Be it known that LE with) WALTER;-

a citizen of ft-he United States,residing-at- New York, in the county of New-York and State of hew York, -hav'e invented certain.

new and useful Improvements ir'i'Type- Writers, of which the following'is'a-specification, re ference being hadt-herein to the accompanying drawing,v i

' This invention relates to typewriters, and

for an object, in one aspect, the temporary actuation of the spacing structureof the typewriter machinein a d actuating 4Q om that offi tsj normal travel, whereby a character (such as an exponent), word or line may be printed'away from the normal printing ointor line; 3

rect-ion different In another aspect of t e invention, the; object is to provide controlling mechanism for the actuation of said spacing structure. A further object is to provide controllable mechanism co-actin of the spacing structure may be varied at the will of the operator.

A further'object is to combine with-such controllable mechanism, means whereby the.

structure may be held in the position to which it may have been actuated,

A further object is so to construct and dispose said actuating and controlling mecha the regular op nisms that, while inactive, eration of the machine is possible.

With these and other objects in view,'the intention resides, amongother features, in a spacing structure of a typewriter combined with the following instrumentalities, severally and collectively, namely, means for said structure ina direction opposite to its normal travel, mechanism for controlling the degree of movement, devices for varying the movement at the will of the operator, and elements and unlocking; the, structure in the position to which it may have been actuated under the action of. said actuating mechanism for returning it" to normal position, and for normal travel.

I

I In these drawings, and referring tothe form of structure shown in Figs. .1-4, the numeral '1 designates a platen-in this instance showmby way of example, as a flatplaten--upon which "the page A is to be spread out in a flat condiotmovement of the writing sheet or tion, and be properly retained inposition thereon, as by a work-confining device B of form and characteristics. Ar-

.track-fiame C comprising rails or guides 3, 3, preferably provided witha rack 3, the

purpose of which will presently appear. .';Adapted to traverse said tracks is a linespacing-carriage D, and this is designed to travelitduringthe progressive operation of printing on=the sheet) from the rear toward the front. In this instance, therefore, the

tracks-are the support for said carriage.

superposed on said line-spacing carriage is a letters spacing carriage E. adapted. to travelat right-angles to the direction of l travel of said line-spacing carriage, and in -15 It will be seen that, by means of these two which .is disposed the writing-mechanism F.

carriages, the writing-mechanism is adapted to travel in two relatively diflt'erent directions overthe platen. The line-space carriage D includes, at each side, a. casing D in which is housed appropriate carriage-proelling and escapement mechanismssuch, or instance, as those disclosed in United StatesYPa'tentNo. 826,483, dated July 17, 1906. The casings D of this carriage include rollers d which are'adapte'd to run on the tracks 3 at one side of the raclis 3". Extending between and journaledin the two casings or housings D is adri've-shaft 4, upon each end of which is mounted a earwheel' 5 adapted to mesh with the rac 3",

' aforementioned. A. power-springfi encompasses the shaft adjacent the gear 5 and, by

connecting with said shaft, 1s adapted to drive the same. ,Appropriate escapemenb mechanism (not shown) for controlling the movement of the carriage is utilized, and may be that revealed in the patent aforementioned.. As it forms no part of the present invention, a, detailed description thereof deemednunnecessary. Also fast on the V right-hand endof the power-shaft, and

spaced from said gear 5, is a toothed wheel 7 adapted to rotate, in the normal travel of the carriage, in a clockwise direction. Normally out of engagement with said toothed wheel but adapted tof be actuated into mesh therewith, (by mechanism presently to be described) is a toothed se ment 8 supported ad'acent the lower end o its actuating-arm 9 lcruined at its lower end on a shoulders'crew 9 and jointed at-its upper end at 9" to the endof a key-lever 10 pivoted at 10 to-the upstanding portionD of the righthaiid casing or housing D of the line-spacing carriage. "Intermediate of the ends of the key-lever 10 is rotatably mounted there- .on a lever-controlling device. In this instanceandiasiillustrated .in Figs. 14 and 6, itr is'in theform of a mutilated dish 11 turning on a horizontal axis ll" and as.

shown in Figs. 2 and 4) is provided with a series of abutment-surfaces 12, 13 and 14,

and '(as shown in Fig.- 6) with abutment surfaces 12, 13, 14 and 15,in eccentric arrangement relatively the axis 11', the. abutment-surface 12 being the nearest and the surface 15 being the remotest from said axis. The urpose of this construction will presently e explained. Adjustably dieposed on the upper portion D of the linespacing carriage is a relatively stationary upstanding abutment or post 16 adapted to be engaged by one or another of the abutment-surtaceson the disk 11 when the keylever 10 is depressed by the operator.

In Fig.6, I have shown a somewhat dif-i ferent form ofadjustable lever-controlling stop. In this instance, it comprises .a thumbscrew 17 threaded in a boss 18 on the side of the lever 10. The lower end" of this screw is designed to impinge against the top of the portionD of the lines'pacing carriage. -By

means of this device, any desired degree ofadjustment is possible, and thereb the movement of the parts may be contro led to a nicety' and within a rather wide range.

Similarly, in Fig. 7, I have revealed another;

modification of lever-controllin device 19,

and wherein I utilize the dis shown in Fig. 3; but omit the plurality of distinct abutments and, in lieu thereof, form its operative periphery as'a continuous andunbroken surface 20- but eccentric with refer- 2-:

ence to the axis 19* of the disk, and any portion of which may be presented (by turning the disk) to abut againstthe post eccentrically-formed periphery to abut against the post- 16 when the key-lever. is depressed. I 7 It will be understood that the lever-controlling device may be disposed in locations other than that shown.

- Occasionally it .is essential or desirable to lock the key-lever: in itsdepressed position whereby the parts and mechanisms which it controls may similarly be locked in their actuatedpositions. To this end, I dispose .a locking elementv in such position thereby, and it may be of many difierent forms. In the construction disclosed in Fig. 3,,I have shown the locking-element in the relatively to said lever that said element may engage therewith or with a part carried form'of a crimped' spring 22 "adapted to-' have on'e or'an'other of its depressions22".

cngagea pin 23 disposed in the side of the lever 10.

In lieu of the construction shown in Fig.

3, as just described, for locking the keylcver 10 when depressed, I may, as shown in Fig. 6, provide an upstanding springcontrolled element 24: provided with Serrations orteeth 24 adapted to engage a sharp edged'dug 24- onzithelower edge of the lever10.l I Referring again to Figs. 2+1, it will be seen that the shoulderrscrew 9 already re ferred to.;.as the the actuatingarm ,9) 1s cari-ied by. the 'a-rigulatediarnii-o pivoted at 26 to. the side ofthehousing D the angular portion of said arm, beyond the shoulder-screw 9,- being designed to rest upon the drive-shaft 4 and thereby constiin actuating the tute. a stop have been actuated, as will presently he explained.

When the key-lever 10 is depressed by the operator, and which results primarily V segment-member 8 into mesh with the toothed-wheel 7, there is, initially-while the teeth onsaid member 8 are moving into engagement with the teethon "wheel 7- some lost 1notion, and advantage is taken of this to effect the actuation of the backwardli under 7 the elongated I that the pawl 27 may be disengagedfrom v has engaged with tinued depression followinggparts: A pawl 27 (which is mounted on a slidable pivot 28 working in an elongated slot 29 in the lower partof the side-plate 30 of the housing D is normally in engagement with the rack 3, asshown in Fig.3, and is designed to prevent the line-spacing carriage from being moved normal conditions. This pawl carries a headed pin. 31 adapted to slide in an elongated slot 32 in a two-piece link 33.fulcrumed at its-upper end. on a horizontal axis 33 formed in a stud 3tcar ried by the lower end ofthe actuating-arm 9. The two-piececonstruction of the link 33 to permit adjustment, whereby the actuation 'ofthe paw ever necessary, as will be understood. The lower portion of the link 33 is provided with slot 32, already'referred to; so

the rack by the general-release mechanism .(not shown) whenit is desired-.150 release 'th carriage so that "t can be moved fireel-y back and forth over the-platen.

Operation: When pressed by the operator,

While this is occurring, the actuatingarm is simultaneously withdrawing the paWlQZT from the rack 3.

for all the parts connecting. therewithwhen atrest, that is, before they 27 may be changed, when-.

the lever 10 is deit actuates. the arm 9 and tends to position the toothed segment,- 8 in engagement withthe toothed-member 7.1:

soon as. sa1d;-paw1. 1.. disengaged from the rack and the segment the member 7. the-con;-

rearward movement 1 The operator predetermines the extent of the movement in accordance with theposi tion at which the printing is to be donegf" that isto say, whether an e'xponlent-cha-ram ter is to be printed, '(as shown by the lower line, Fig. 2)- in which instance, the controlling-disk .11 is turned to present thejalnit I merit-surface If) in position to engage the post 16; or if an interlineation (such as indicated by the middle line of printing in Fig. 2) is tobe made,.,- then the. disk is turned to present the surface 14; inposi-tion;

an d so on. It is to be understood thatthe linespacing carriage is adapted to have variablespacing, as already mentioned. Therefore, I have prov ded the controlling disk -11 with abutment-surfaces to correspond with" the several degrees of spacing so that, in the event the carr age 1S set for single spacing,

it can be actuated rearwardly to correspond with that "degree of spacing. If, on the other hand, it is set for double spaciifg, the disk is similarly set.

I And if the carriage is adjusted for treble spacing. then the disk will be set correspondingly. In other words, the travel of the carriage is always for an even ratio. For instance, for a single linespace, the carriage would move approximately three-smteenths of an inch; for

double-spacing, the travel would be for sixsixteenths of an inch, and for treble-spacing, thetravel would be nine-sixteenths of an inch. Therefore, the teeth in the gear 7 will always stop at the same position, and this enables me to effect a rearward actuation of the writing-mechanism with accurate regard for the degree ofspacing riage is set to. travel; the rearward movement of the carriage (and, thus, of thew-riting-mechanism carried thereby) being ifor a predetermined distance,-and' this will position the writing-mechanism above the print- 7 ing point on the platen 'and a distance there from according to how the controlling;- disk is set. It will be understood, ther.efore, that the key-controlling member (such as the disk 11 is positioned that the carto govern the extent I of depression of the ke'ylO and, thus, .the' I extent of rearward movementpf thegacar- -riage according to the degree of spacing for which the carnage has been setto travel forwardly. In consequence, if the carriage-; {spacing is set forysay, a single-space the described. "would be positioned to regulate thev oi movement of the key 1.0. and of the ,car- -.riage)" 'with in that spacingedistance. If the carriage actuating mechanism extent carriage is set to space the widest of its possible spacing," said carriage-aqtrlati ng mechanism is correspondingly set to control the rearward ,moyement anywhere within that spacing-distance. Beyond such-predetermined spacing-distance, the carriage is not permitted to move. In'other words, the

s never beyond} the I will return the carriage to normal position.

Ordinarily, the carriage-actuating mecha-' nism will be in inoperative osition, and is,

in the manner already exp ained, actuated into operative position by'means of the keylever which, in such instahce, becomes a conactuated bac '30 namely, normal ward for its s acing movement, and,.also,'

trolling device for the back-spacing mechamsm.

It is to be understood that the carriagedriving mechanism (including the powerspring 6) is constantly active to move the carriage forward in the direction of its norma-l spacing movement. When the carriage;

returning-mechanism (including the lever;

is actuatedby the operator, the carriage is moved backward in a direction opposite to such normal travel and is, thus,actuated against the action of said carri-age-driving-.

mechanism. In consequence, the instant the carrlage-returmn .-mechan1sm becomes mactive -as when t e operator removes his finger from the lever 10 to ermit it to re.-

turn to normal position-sai carriage-driv:

ing-mechanism moves the carriage forward again to the osition it occupied when it was ard ing-mechanism; e carriage driving mechanism has therefore, two i functions,

ly to drive the carriage for- ,torestore sai 'carria e to position after beingmoved backwar turning-mechanism. y

Should it be desired to write more than a single character "when the writing-mechanism is actuated, as already explained, and in order that the operator may not be obliged-to hold the key-lever 10 in its de'- pressed position during the writing of one or more characters, the locking device (designated 22 in Fig. 3,'and 24 in Fig. 6) is utilized and whereby the key-lever 10 will be-locked in its depressed position temporaril By this means, as the key-lever 10 is ocked inits depressed-position, so

also will the writing-mechanism-supporting carriage be locked in the position to which it is actuated. As soon as the said keylever .is released, either by the removal therefrom of the operaltorsffin er, or by disengaging the aforementi'tuie' lockingdevice therefrom, the carriage-under the action of the carriage-propelling spring 6 will automatically be returned to normal position-from which it had been actuated'and, thus, be restoredto the normal line of writing.
